Seems like quite a waste when you could simply use WoL (wake on LAN). The article says that WoL only works when the computer is suspended, but that is not true.

EDIT: I was unaware that Microsoft has deliberately disabled WoL in Windows 8 and above. You could work around this by booting Linux before shutting down the computer.

There are other situations where WoL may not work: A desktop computer that uses Wi-Fi and not Ethernet. Unlikely, I know. But possible.
